2 Claims. (01.107528) work, and also to lessen the number of attendants required in operating themachine. This is accomplished by a change inthe part of the construction having to do mainly with the delivery of cakes in successive transverse rows-to a depositing mechanism which delivers toeach cake a measured quantity of one or more coating substances, such as marshmallow, or the like.

In the machine as described in the above mentioned patents, there is a receiving platform upon which the cakes are sorted out by hand and pushed on to an upper shelf of a series of steppedv shelves which are surfaced with relatively reciprocating shelves and the reciprocating shelves alternately slide rearward beneath the cakes re-v ceived thereon and then forwardly engaging the edges of the cakes and pushing them over the edge of a step to the one beneath it. f

By a series of such actions the cakes are Worked forwardly to the depositing means and broughtV into proper alinement therewith and while on the way defective ones arediscarded by hand and the spaces filled with other cakes so as to insure the absence of any blank spaces. It is also necessary to see that none of the cakes go in upside down. Thus the machine required the attention of several operators.

Now it is proposed to. provide the machine with a supply magazine whichreceives thewcakes or 40 cookies in vertical rows and with an improved feed mechanism which automatically. separates and properly spaces the cakes on a single belt. The belt carries the cakes forward to a receiving means which reciprocates to place the cakes row by rowy beneath the depositing mechanism.

The purposes of the invention are attained by means of a mechanism as illustrated in the accompanying drawings wherein: y y

Fig. 8 is a fragmentary sectional view taken on the line 8 8 of Fig. 7. v Y l Fig. 9 a diagrammatic detail of vpart of the main drivegmechanismf 1 @The Westermanadepositingy machines are of heavy construction Vbecause ofthe over-all dimensions thereof, and the necessity of operating upon extremelyhviscous material, but such` part of; theY machine towhich the present invention relates, and having to do merely with the spacing and feedof the objects coated, maybe relatively light andreasily. capable of maintaining a `speed coordinated with the maximum ,speed at which the plungers in the .depositing mechanismmay be operated'. Y I l The old parts of the machine, which are not detailed herein, but which are described in the before mentioned patents, include mainly a multiplehopper construction containing the various` viscid coating xmateria1s together Vwith feed plunger, measuring and: cutoff devices.

One Vpeculiar requirement of the machine is 35 that-.after. the cakes lhave been coated itA is necessary to move the cakesl downward away from the coating means before the cakes are movedk forward toward the discharge end of the machine. This is necessary because of the elas- 40 ticity of the coatingkmateriaLand it isnecessary to break the threads thereof by a downward pull, so that no part of the coating material will fall over on the edge of 4the cake. n

With this requirementin View the feed belt 4- which carries the cakes from the supply magazine and a belt which `receives the cakes are mounted upon a frame structure which swings up and down around a center at one end.

, The belts of the machine are driven by ratchet v50 mechanism to impart, intermittent motion thereto` in a continuous direction. Other cooperating feed devicesof the machine are reciprocating. These devices. consistofa 1serrated slides,` one of which removes `the lowermcstlcakes .from the Y supply magazine chutes and the other of which receives the lateral rows of cakes, one row at a time from the belt and places them beneath the coating nozzles.

The main frame I of the machine, Fig. 1, supports at its front end a magazine 2, formed by a number of separable chutes for the rows of cakes which are placed in or mechanically fed into the upper end of the magazine. The chutes 3 are flanged, as shown at their forward ends 4 and are secured to a rear plate 5 of the maga- The cakes are therefore guided by walls on all four sides as they move down by gravity to a supporting plate E, Fig. 3. The mounting for the magazine permits both of its rapid removal and replacement by a magazine of different form, and its adjustment vertically, laterally, and forwardly and rearwardly, in a support 1, for the purpose of correctly positioning the magazine with reference to a serrated slide 8 which travels back and forth over the plate 6 for the purpose of removing the lowermost series of cakes from the magazine and placing them` in a horizontal transverse row on a belt 9. Some of the cakes are indicated on the belt at I0 and coated ones at I on a discharge belt l| I.

The drive mechanism for the belts 9 and I, the serrated feed plate 8 and a similar serrated plate I2 which receives and places the cakes beneath the coating spouts, receives power from a motor I3, Fig. l. This motor through a speed changing and reduction gearing in casing I4 drives a sprocket I5. The sprocket I is connected by a chain I6 with a sprocket'll which is loose upon the main drive shaft I8.

Rotatablc with the sprocket I1 is a sleeve I9, Fig. 6, which carries a clutch for connecting it with the shaft I8. This clutch is operated by hand lever 2|, Figs. 1 and 2. When the clutch is in and shaft I8 is driven, motion is transmitted from shaft I8 to another drive shaft 22, Fig. 5, through the pinion 23 and gear 24. Shaft 22 carries an eccentric 25 by means of which a pitman 26 is reciprocatedand serves to oscillate arm 21 fast to a transverse shaft 28. This shaft carries the arms 29 which at their upper ends are linked by the threaded rods 30 to collars 3| swiveled at the sides of a transverse bar 32 to which the serrated feed plate 8 is attached. The stroke of the pitman is regulated by screw 33, and the nuts 34 on the threaded bars 30 enable forward and backward adjustment of bar 8, with reference to its operating mechanism.

The serrated feed bar 8 serves to successively place uniformly spaced rows of cakes on the feed belt 9 which carries the cakes to the serratedplacing bar I 2. 'Ihe drive roller 36 for the'belt 9 is fast to a transverse shaft 31. This shaft is intermittently driven, in the direction indicated by arrow 35, through the ratchet 38, Fig. 2, and a' link connection 39 with crank 40 fast to shaft 22.

The belt 9 is guided around rollers 4| and 42 and around a transverse plate 43, all of which are supported on a frame structure 44 which is supported at one end on shaft 31, and may oscillate up and down around this shaft.

The forward end of the frame 44 through posts 45 which are pivotally connected with the frame, rests upon arms 48 which are keyed to a transverse shaft 41. This shaft is oscillated to swing the frame Yor table structure 44 up and down around the shaft 31 by a cam 48, which is secured to a drive shaft 32', and operates on a roller 49 carried by arm 50 fast to shaft 41.

The connection between arms 46 and the'posts 45 are the pins 5I on collars 52, shown in Fig. Il. These collars may be shifted up and down on the posts 45 to change the effective length of the latter by means of sprockets 53 which carry the collars, and are threaded to the posts,

and connected together by a chain 54. The latter is xed to fork 55 which is used for operating the chain to effect vertical adjustment of the table 44, by means of a rod 56, having the operating handle 51, Fig. 1.

The toothed pusher plate I2 is slidably mounted between the belt 9 and a belt II and when the pusher plate I2 is in its rear position a row of cakes passes from plate 80 which receives from belt 9 to belt |I at locations which bring the cakes between the teeth of the pusher plate when the latter advances and positions the cakes beneath a row of nozzles 59. The coating material is fed through nozzles onto the cakes when the latter are so positioned.

The means for reciprocating pusher plate I2 includes plate which is flanged around the sides of plate I2 and carries a transverse bar 6| for engaging the back of plate I2. 'I'he means for reciprocating the pusher 'plate holder, Figs.

2, 3 and 4, are the oscillating arms 62, one of which has an operative link connection 63 with the pitman 39. The reciprocating holder 60 is connected to the upper ends of arms 62 by connections with links 64 pivoted at 65 to arm 62. The pivot is carried by a collar 66 and by means of the nuts 61 links 64 may be adjusted in the collar for the purpose of positioning the plate holder and hence the plate I2 forwardly or rearwardly with reference to its operating mechanism. This adjustment is needed because the toothed posi-V tioning plates l2 are varied in form and size according to the size and form of the cakes it is desired to have the machine work on.

The reciprocating plate holder 60 slides along ways 68 on the pivoted frame 44 and through screws 58 is secured to bar |06 having ears |01 pivoted to'element 64.

In order to replace toothed plate I2 by another it is necessary to lift the holder 60 and in order to get the belt supporting plate 43 out of the way the latter is mounted on a structure 69, Fig. 7, which is pivoted by bolts 18 to the frame 44. The structure 69 carries toothed segments 1| at its sides which mesh with pinions 12 on a shaft 13 in frame 44. By placing a wrench on one of the square ends of shaft 13 the shaft maybe lrotated to lift structure 69 and the belt guide 43 carried thereby.

Belt 9 is tightened by means of screws 14 acting upon the belt guide plate 43 and belt is tightened by adjustment screws |08 acting on bearings |09 for belt roller 16.

The belt is also intermittently operated and timed so as to be at rest during the intervals that coatings are placed upon the cakes when beneath the spouts 59. The belt travels around the rollers 16, Fig. 4, and 16', Fig. l. The driven roller 16 istrigid with a ratchet 11, Fig. 7, which ratchet is engaged by a pawl 18 on the arm 19 and the arm 19 is oscillated around the roller support by a link 88 connecting it with an arm 8|, Fig. 2, pivoted at 82 and rigid with arm 83 connected by link 84 with an operating arm 85 pivoted to the machine frame at 86.

Roller 81 on arm 85 is engaged by eccentric 88 carried by a transverse shaft 89. This shaft is connected by gearing 90,A Fig. '6, with drive shaft I8. The same gearing serves to drive shaft 22 which is not made continuous with shaft 22 in onwardly to the discharge e'nd of the machine; but the movement of the cakes away from nozzlef order to allow for quick removal of cam 48 andA replacement with another of different throw.

The supply of coating material is carried by hopper construction 9| and the plungers for forcing measured quantities of the material through the nozzles 59 are operated by the vertically reciprocating bars 92, Fig. 2. At their lower ends, these bars are adjustably connected to arms 03 fast to shafts `04 and 95, Fig. 4, and these shafts are oscillated by crank connections 06 with a gear l meshing with gear 98 on shaft 89.

A transversely extending angle iron |00 carries a series of spacing fingers |0| having the function of lining the cakes as they leave belt 9 and are placed on pusher plate holder 60.

When the frame 44, Fig. 4, is oscillated around the shaft. 31 in order to carry the cakes downwardly away from the depositing nozzles 59, belt swings downwardly around the forward supporting roller therefor 76', Fig. 1.

The intermediate guide rollers |02 and |03 for belt are carried by the frame structure 44 and thus move up and down with the frame. Beneath the belt I is another belt |04 which is supported on a separate detachable frame |05 and has the function of supporting trays at the delivery end of belt ll for receiving the coated cakes in rows and for this reason belt |04 is intermittently driven by ratchet H0, Fig. 2. The trays are placed on belt |04 beneath the belt Il and are removed from the belt |04 after they have passed beyond the delivery end of belt Il.

In the operation of the machine, the cakes for receiving deposits are fed by gravity from magazine 2 to the supporting table 6 from which they are pushed in rows onto belt 9 by the serrated pusher plate 8. The belt carries the rows of cakes placed thereon step-by-step forwardly to between the alining fingers |0| at which point the cakes pass from belt 9 to support 60 and to belt which is also intermittently driven and, as aided by the serrated pusher plate i2, serves to bring the rows of cakes successively beneath nozzle 59 and to pass the deposit carrying cakes 59 is first downwardly' so that the threads of de-r posit material Will be broken in this directiorr and not tend to drop over the sides of the cakes.

This downward movement is accomplished by rocking frame 44 around axis of shaft 31 and as the frame constitutes the support for one end of. belt Il, the belt is swung down around its end supporting roller 10', Fig. 1.

This rocking belt supporting frame structure enables the necessary actions to be performed with rapidity and accuracy without the use of the stepped reciprocating feeding means heretofore used on the Westerman machine.

We claim:

1. A depositing machine of the class described having mounted thereon a supply magazine for the objects which receive deposits and a depositing mechanism, a belt carrying frame mounted on said supporting frame for oscillation thereon and beneath said magazine and said depositing mechanism, driven belt supporting rollers and belts thereon carried by said belt supporting frame, one belt being located below and extending beyond the other, means for intermittently driving said belts, and pusher bars operating in timed relation with said belts for removing the objects for receiving the deposits in successive rows from said magazine and for aiding the belts in placing said objects beneath the depositing mechanism.
